Programmatic Sales Order & Back-to-Back PO Creation
When creating a Sales Order via the API, OpraOne automatically resolves the customer's contract Price Book tier, locks warehouse Available-to-Promise (ATP) stock, and optionally triggers back-to-back vendor Purchase Orders for any drop-ship or shortfall SKUs in a single atomic transaction.
